Studies on the chemical constituents of Fructus Ailanthi altissimae

Aim To study the chemical constituents of the 95% EtOH extract of the fruits of Ailanthus altissima (Mill.)Swingle. Methods The chemical constituents were isolated by chromatography and identified by spectral data and literature. Results The compounds obtained were identified as stigmast-4-ene-3,6-dione(Ⅰ), β -sitosterol(Ⅱ),6 β -hydroxystigmast-4-en-3-one(Ⅲ),5 α ,8 α -epidioxyergesta-6,22-dien-3 β -ol(Ⅳ),stigmast-4-ene-3 β ,6 β -diol(Ⅴ),9,19-cyclolanost-23( Z )-ene-3 β ,25-diol(Ⅵ),3-epi-ursoloic acid(Ⅶ),12 β ,20( S )-dihydroxydammar-24-en-3-one(Ⅷ),daucosterol(Ⅸ). Conclusion Among them,Ⅰ,Ⅲ,Ⅳ,Ⅴ,Ⅵ,Ⅶ,Ⅷ and Ⅸ are isolated from this genus for the first time.
